Condition type should be ignored if price is 0.

I have a price condition type wherein the scale value is maintained such that if qty is less than 100pcs., price is 0 and for quantity above 100, the price is 10EUR. My requirement is that when the quantity is less than 100pcs., then the other price conditions should get determined. As scale is mainatined here, the conditon record is found and price picked is 0. Also, further price conditions are not checked as condition record has been found. How can I ignore this condition when price is 0. Please advise
